226 LLOYD’S NATURAL HISTORY. 
Habits——According to Temminck this bird is by no means 
rare in Paraguay, where it is known under the name of 
‘Vacuhu.” It is most commonly met with in the forest 
regions in the neighbourhood of rivers and lakes. Its cry con- 
sists of the syllable yac, repeated several times and given forth 
in a high key, and it occasionally calls “yacu,” from whence it 
derives its name. 
In Lower Uruguay, Mr. W. B. Barrows found this species, 
the “‘Pavo del Monte,” limited to the borders and islands of 
the river, where in heavy growth of timber it was not uncom- 
mon, though rarely seen. It has a very harsh, cackling cry. 
The flesh is much esteemed, and the bird is easily domesti- 
cated. 
Nest.—Said to be a bulky structure placed in trees, 
Eggs.—Said to be eight in number; white, and laid in the 
month of October.
